this is how I do it :

Thanks for that Franco.

Franco

Do you have a recipe for polyester? I can only find reference to proprietary brands rather than home made.

Noi I don't , but I believe that Kwick Grip/Tarzan Grip are pretty much the same stuff as Seam Grip
polyurethane polymer
Seam Grip can be thinned with Cotol 240 (also a McNett product)
That stuff is "METHYL BENZENE and DIBUTYLBIS STANNANE" whatever that is....
it can also be thinned with toulene (toluol)

look there under "solvent"

When I used to seam seal with Seam Grip I did not thinn it but it was a bit of a pain and never looked all that neat.

Thanks for your reply Franco

It sounds like it would be a lot less fuss just to buy a bottle of the proper McNett seam sealer.

Thanks again

Is white spirit (not shellite) ok instead of turps or is turps better?
Turps is on the nose and white spirit not so bad.

Damn i wish i saw this about a month ago. Had a hell of a time thinning the stuff

What's the difference b/n home made sealant cocktail per above vs commercial products eg. Seam Grip? Have my first seam seal job coming up.

SeamGrip isn't silicone, it's a urethane glue. You may be thinking of SilNet, made by the same company (McNett). It's a silicone sealer. As to what the specific differences are I can't say, but I will attest to noticing differences. SilNet works very well as a seam sealer but when I tested it against an aquarium glass silicone adhesive for gluing together pieces of silnylon fabric, SilNet didn't make as strong of a bond as the other product. So something was different.

Thanks Orion. Didn't know the urethane base on the SeamGrip. So question remains, what's the criteria one should use in deciding b/n a home silicon cocktail and SeamGrip? Is one more durable than the other? Effect on tent fabric?

Use a silicone (not silicon) product on a silicone impregnated fabric. Otherwise use SeamGrip or something equivalent.

oops

Thanks. Indeed it's silicone. Missed one letter... Ummm... I think Tarptent's recommendation is to go silicone based.

Tarptent is silicone coated fabric so like Orion said go with silicone.

Glad I reviewed this point with you guys. Thanks. A stop at Bunnings is due this evening on the way home.

Ah...i might have used silicon... i didnt know there was a difference.lol!
